Abstract

Araucaria cunninghamii is one of the endemic needles tree species grown naturally in Papua. The material used in the study is wood of A.cunninghamii that was planted in the first-generation of progeny test in Bondowoso, East Java. This study aims to determine the characteristic chemical properties of A.cunninghamii wood from some provenances as raw material for pulp. Disk of wood samples were taken from the stem at 50 cm above the ground with 5 cm of thickness. Testing chemical properties include the levels of toluene extractives soluble in ethanol, hot water soluble extractives, holocellulose, cellulose and lignin. Data were analyzed to determine the effect of provenance to chemical properties of wood. The results of study showed that wood sample of A.cunninghamii contained 73.33% holocellulose, 46.39% cellulose, lignin 30.56%, 1.19% ethanol solubility and 1.34% hot water solubility. Based on the composition of chemical substances contained in the wood, A.cunninghamii generally has good quality to be used as raw materials of pulp and paper.

Abstract

A Provenance test for ex-situ conservation and a progeny test of Eusideroxylon Zwageri was established in 2006 and 2008 at Sumberwringin, Bndowoso, East java. The trials were evaluated every year to examine genetic and environment effects on growth. There significant differences among provenances for height both at the provenance and progeny test. The differences among families within provenance was statistically significant for height and diameter. Estimated individual heritabilities at one year old for height and diameter. Estimated individual heritabilities at one year old for height and diameter r=were hight (hi2 = 0.58 for height and hi2 = 0,52 for diameter).

Abstract

The estimation of genetic parameters for stem diameter and plant height of ironwood (Eusideroxylon zwageri T. et B.) was conducted in a progeny trial in Bondowoso, East Java at the age of 5,5 years. The trial was arranged in an incomplete block design, which comprised of 49 families from three provenances (Batanghari, Berau and Kutai Kertanegara) with 4 replications and single tree plot. Families of Batanghari provenance showed the best growth of stem diameter and plant height compared with another provenance. There was significant difference in plant height between families within provenance, whereas stem diameter was not significantly different both of between provenance as well as between families within one provenance. Non-genetic or environmental factors provide considerable influence on plant growth in the progeny test of ironwood until the age of 5.5 years; it was indicated by the residual variance component. Individual heritability for plant height was considered as high (0.37) and stem diameter was considered as moderate (0.26). There was a strong genetic correlation between the stem diameter and plant height (0.95). This information is very important for future genetic improvement of ironwood.

Abstract

ABSTRAKUji keturunan A. mangium generasi pertama dari Papua New Guinea and Queensland-Australia telah dibangun di Wonogiri - Jawa Tengah pada Desember 1993. Seleksi pohon di dalam famili telah dilakukan menggunakan variabel pertumbuhan, namun belum menggunakan variabel sifat-sifat kayu.  Tujuan dari penelitian ini adalah untuk mengetahui pengaruh provenans maupun famili terhadap keragaman diameter dan sifat-sifat kayu A. mangium tersebut pada umur 5 tahun. Hasil penelitian menunjukkan bahwa berat jenis kayu tergolong sedang yaitu rata-rata sebesar 0,44 dan panjang serat tergolong serat pendek yaitu rata-rata sebesar 1,04 mm. Di uji keturunan A. mangium tersebut terdapat keragaman antar famili di dalam provenans dan keragaman antar provenans pada sifat prsentase kayu teras, berat jenis kayu, dan kadar air.  Heritabilitas individu untuk diameter batang dan persentase kayu teras sangat rendah (h2i=0,03 untuk diameter dan h2i=0,05 untuk persentase kayu teras), sementara sifat-sifat kayu mempunyai heritabilitas individu yang tergolong rendah  sampai tinggi yaitu h2i=0,10-0,56. Hasil dari penelitian tersebut mengindikasikan bahwa seleksi pohon menggunakan sifat-sifat kayu seharusnya dilakukan untuk meningkatkan kualitas kayu.  ABSTRACTFirst generation (F-1) of progeny trial of Acacia mangium originated from Papua New Guinea and Queensland-Australia was established in Wonogiri, Central Java on December 1993. The tree selection within family  were carried out base on growth characteristic, whereas the wood property traits were not included. The objective of this research is  to find the effect of provenance or family in variation of diameter and  wood properties  of`A. mangium in the trial in 5 years old. The results showed that mean of wood specific gravity was 0.44 (it was medium catagory)  and mean of fiber length was 1.04 mm (it is short fiber category).  Variation of heartwood area, wood specific gravity, and moisture content showed significantly differences among provenance or between family within provenance.  Individual heritability of diameter and heartwood area were low (h2i=0.03 for diameter and  h2i=0.05 for heartwood area), however individual heritability of wood properties were low to high (hi2=0.10-0.56). The result of investigation indicated that trees selection using wood properties  should be conducted to improve wood quality in the progeny trial.
